A gear is defined by its mating element, not just its outside diameter. A worn sample can help, but the assembly should be reviewed before reproducing it.
Typical applications
- Power transmissions and feed mechanisms.
- Replacement of pinions, gears or racks in existing equipment.
What we review
- Tooth geometry, tooth count and mating element.
- Diameters, width, bore and fastening method.
- Material, load conditions and assembly condition.
What you can send to get started
- Drawing or sample and, if available, its mating gear.
- Required transmission ratio or original equipment information.
If you do not have a drawing, share what is available. A worn sample is reviewed alongside its mating surfaces and components; it is not assumed to retain the original geometry.
